Expert Advice: How to Get Shiny Hair

QUESTION: My hair seems so dull. How can I make it look healthier?

ANSWER: First, determine why your hair looks less than lush: Perhaps you colored it but haven't been using color-protective products. Or maybe you have product buildup -- the result of applying too many styling aids and not removing with the right shampoo. Or it might be the result of daily damage from overstyling. Once you have identified a culprit (or two), use the advice below in your routine regularly, advises Paul Labrecque, creative director of Paul Labrecque Salon and Spas in New York City.

• Heat-style wisely. "Heat flattens your hair's cuticle (the outer layer of the hair shaft), allowing light to reflect off it and create a glossy finish," Labrecque explains. But when used improperly (for example, heat-styling without a protective product), hot appliances can burn the hair strand. Labrecque's advice: Spritz hair first with a product that coats the hair. We like Tresemmé Instant Heat Tamer Styling Spray ($4; at drugstores).
• Avoid overprocessing your hair. Add color or highlights as needed, but not more than once every four months. Then, post-processing, try products specifically designed for color-treated hair; these are gentler and less likely to strip your strands of their natural shine-inducing oils. Editor's pick: color-specific shampoos and conditioners from John Frieda ($6.50 each; at drugstores), available in Sheer Blonde, Brilliant Brunette and Radiant Red.
• Read the ingredient label. "Some styling aids contain alcohol, which can dehydrate hair and make it look dull," Labrecque says. Instead opt for creamy, water-based products. Try Paul Mitchell Express Style Quick Slip ($13; paulmitchell.com) or Dove Straight & Soft Sleek Styling Cream ($4.29; at drugstores); both tame the frizzies while keeping hair vibrant and healthy.
• Pro tip: Use clarifying shampoo twice a month to rid dulling product residue.
